Summary: I love my P770 in terms of performance, and screen image quality. My only disappointment is that about a year after buying it, it started to overheat and shutdown (I am indeed a heavy application user), so I had to get a Cooling Pad (thermaltake), it helps, but the palm-rest area to the left of the mouse pad still gets hot (where the HD is). Battery life is so-so, I can get 2h of video out of it, max bright. no wifi.
Excerpt: I work from home for a consulting firm online and needed a laptop that was fast, durable, plenty of memory, large enough screen for working on for more than 8 hours a day, the ability to hook up an external monitor but also be able to pack it up and take with me should I need to work elsewhere at any time. Basically I needed an affordable desktop replacement laptop and I sure got it with the Toshiba P-770!
